European refrigeration systems hacked in wave of cyber-attacks

Hackers have raised temperatures in supermarket and blood-storage refrigeration across Europe, prompting EU officials to prepare a collective response.

• France's national blood service said hackers raised temperatures at three cold stores overnight Monday before technicians intervened.
• Hackers raised temperatures in supermarket refrigeration systems across at least 11 European countries, spoiling tonnes of food.
• EU spokesperson Thomas Regnier said the incidents were "not isolated" and that the bloc is developing a collective response.
• Romania's cybersecurity director Dan Cimpean said he does not suspect a state actor behind the attacks.
